The 4116R-1-391 is a thick film isolated resistor network manufactured by Bourns Inc. These networks contain multiple isolated resistors within a single package, saving board space and simplifying circuit designs. This particular part is not marked as lead-free, which may indicate it was manufactured before RoHS standards were universally adopted.

Applications

• Current limiting
• Voltage division
• Pull-up/pull-down resistors in digital circuits
• Input protection for operational amplifiers
• Logic circuit termination

Features

• Isolated resistor configuration
• Thick film technology
• 16-pin package
• Stable resistance values

Benefits

• Conserves board space compared to discrete resistors
• Simplifies circuit layout
• Improves reliability by reducing solder joints
• Reduces component count

Additional Details

The 4116R-1-391 has a resistance value of 390 ohms. The '391' marking uses a standard EIA code where the first two digits represent significant figures, and the third digit is the multiplier. Isolated configurations have each resistor electrically isolated from all other resistors. It has a power rating (check datasheet for specific value, typically ~0.25W per resistor). This component is likely intended for through-hole mounting. Resistance tolerance depends on the manufacturing tolerances, but is typically around ±2% to ±5%. The temperature coefficient of resistance (TCR) is a critical parameter for resistor networks to guarantee resistance stability, usually around ±100 ppm/°C.
